In the 18th century, Franz Mesmer, an Austrian physician, introduced animal magnetism, a theory suggesting that an invisible force could be harnessed to heal ailments. While Mesmer’s ideas were later debunked, his work laid the foundation for modern hypnotherapy.

During the 19th century, Scottish surgeon James Braid coined the term hypnosis, distinguishing it from Mesmerism. He recognized it as a psychological phenomenon rather than a mystical force and began using hypnosis for pain management and surgery. Around the same time, French neurologist Jean-Martin Charcot and psychiatrist Pierre Janet explored hypnosis as a tool for treating hysteria and psychological disorders.

In the 20th century, hypnotherapy gained credibility through the work of Milton Erickson, an American psychiatrist who developed Ericksonian hypnosis, a more flexible, conversational approach. His work influenced modern therapeutic techniques, including cognitive-behavioral therapy (CBT).

Today, hypnotherapy is widely used for pain management, stress reduction, trauma recovery, and habit control. With ongoing scientific research supporting its effectiveness, it continues to evolve as a respected complementary therapy in psychology and medicine.
